Abstract
A retrospective review of 81 emergency department patients was performed to determine
the accuracy of blood ethanol levels (BEL) calculated from serum osmolality. The osmolar
gap (measured — calculated serum osmolality) was used to determine the calculated
BEL. The mean difference between calculated and measured BEL was 49.2 mg/dL. Calculated
BEL overestimated measured BEL in 83% of patients. Adding a correction factor for
unmeasured osmoles to the equation for calculated serum osmolality will reduce this
error.
